User Authentication With Express and Mongo
Learn how to implement a custom user authentication system that controls users access to web resources using Node.js using Express and MongoDB. The system lets users sign up, log in, and log out, limiting access to password-protected resources. Express is a popular web framework for creating MVC applications and RESTful APIs in Node.js. Express lets developers define routes and middleware for submitting and retrieving data in our database. We will leverage the document based NoSQL database, MongoDB, to store our user data by creating a user model with mongoose. Mongoose is an open source Node package for defining data models for an application and connecting to MongoDB.

Debugging JavaScript in the Browser
JavaScript programs are mysterious and hidden realms where magic happens. This can be delightful when everything is working. During development, though, things often won't work so well, and understanding why can be hard. You need a way to dispell the fog and see everything clearly. In this workshop we'll learn how to use a tool that professionals rely on to get crucial insights into their JavaScript programs: Chrome's Developer Tools (DevTools). With DevTools, you can get amazing access to the inner workings of your program while it runs, controlling how it executes with fine-grained control. This means that once you learn the DevTools arts, you can find and fix problems in a snap!
